Thailand is going digital — and so should you
When I first arrived in Bangkok back in 2018, I remember filling out the old paper arrival card while balancing a tray of airplane food on my knees. My pen didn’t work, my passport kept sliding onto the floor, and by the time we landed, I had already made three mistakes. Fast-forward to 2025 — and Thailand has finally ditched the paper chaos in favor of something smarter: the Thai Digital Arrival Card (TDAC).
If you’re planning a trip to Thailand in 2025, there’s a new box to tick before takeoff. Starting May 1st, 2025, all foreign travelers will need to complete the TDAC online before arriving in the country. No more scribbling on forms mid-flight — this change is part of Thailand’s push toward a fully digital immigration system.
Official TDAC Introduction Video
Watch the official introduction to Thailand’s Digital Arrival Card — This video, published by the Thai Immigration Bureau, explains how the TDAC works and what travelers need to prepare before arriving in the country.
What is the TDAC, exactly?
Purpose and benefits
The TDAC is Thailand’s new mandatory online arrival registration system. Think of it as a virtual replacement for the old paper form you used to fill out on the plane. Instead of fumbling with a pen at 30,000 feet, you now fill out a short form from your phone or laptop 24–72 hours before your trip. It’s fast, free, and crucial if you want to avoid surprises at immigration.
Who needs to fill it out?
Types of travelers concerned
Short answer? Everyone who isn’t Thai. Whether you’re flying in for a beach holiday, coming for business, retiring under a long-stay visa, or simply transiting through Bangkok for a few hours — the TDAC applies to you. No exceptions (yet).
Why is this happening?
Goals of the digital transition
Thailand’s moving toward a streamlined, paperless system to improve security, reduce wait times, and make life easier for travelers and border officers alike. The TDAC allows immigration to pre-screen passengers and process arrivals faster. Plus, it’s one less form to forget at home.
How do I complete the TDAC?
Step-by-step process
Here’s your mini checklist to get it done in under 10 minutes:
- Go to the official TDAC portal: tdac.immigration.go.th
- Enter your passport and personal info
- Fill in your flight number, date of arrival, and address in Thailand
- Upload a passport photo or scan (if required)
- Submit and save your QR code confirmation
Tip: Screenshot your QR code or save it in your email. You’ll need to show it at immigration on arrival.
What if I forget?
Consequences of missing the TDAC
Showing up in Thailand without completing the TDAC could mean long delays at immigration — or worse, being denied entry. Airlines might also refuse boarding if your arrival card isn’t submitted ahead of time. Don’t risk it. Be especially cautious of unofficial websites that charge a fee or ask for personal data.

Any exceptions?
Current exemptions and updates
As of now, the rule applies to all foreign nationals. Thai citizens are exempt, and there may eventually be exceptions for diplomats or border commuters, but nothing official has been announced yet.
TDAC vs. visa — what’s the difference?
Comparison with traditional visa requirements
The TDAC is not a visa. If you’re from a country that requires a visa to enter Thailand, you’ll still need to apply for that separately. The TDAC is simply a new arrival protocol — like filling in your passenger locator form — and it’s required whether you need a visa or not.
What makes this good news?
Advantages of the new system
Despite being a new task on your pre-travel checklist, the TDAC is actually a smart move. It speeds up border control, removes paperwork, and reduces errors. More importantly, it reflects Thailand’s growing commitment to modern, efficient, and secure tourism infrastructure.
Before you fly: final tips
- Submit your TDAC at least 48 hours before you travel
- Double-check your info before hitting “submit”
- Keep your QR code handy — print or digital
- Ask your airline if they check for TDAC at check-in
- Don’t assume it’s optional — it’s not!

FAQ: Thai Digital Arrival Card
Do I still need to fill out the TDAC if I have a visa?
Yes. Whether you have a tourist visa, a business visa, or a long-stay visa, the TDAC is still mandatory. It’s a separate requirement from your visa application.
Can I submit the TDAC on the same day I travel?
It’s not recommended. Ideally, complete the form 24 to 72 hours before your departure to avoid delays or issues at check-in. Some airlines may require confirmation at the gate.
What happens if I enter incorrect information?
If you make a mistake, it’s best to submit a new form as soon as possible. Double-check all your details before hitting “submit” to avoid complications upon arrival.
Do children need to fill out a TDAC?
Yes. Every foreign traveler, including minors, must have their own TDAC completed by a parent or guardian.
Conclusion
The Thai Digital Arrival Card is the new reality for travelers entering Thailand in 2025 and beyond. It’s free, simple, and a necessary step toward a smoother, smarter arrival experience. Get it done early — and get ready to enjoy your time in the Land of Smiles without stress at the border.
